Abstract: Volume II/24 presents the spectroscopic data on diamagnetic and paramagnetic molecules as well as on molecular ions and radicals up to date considering the publications up to and partly including 1997. The spectroscopic information collected in this volume has been obtained principally from gas phase microwave measurements. Volume II/24 is a supplement to volumes II/4, II/6, II/14, and II/19 and is planned to appear in five subvolumes, the last of which will contain the substance index taking into account all molecules worked at since 1967 in the volumes mentioned and will provide cross references to and between all tables of these. The present subvolume II/24B contains an introduction and tables of rotational and centrifugal distortion constants of asymmetric-top molecules, i.e. data which roughly specifies the frequencies of the rotational transitions of these types of rotors.

Abstract: Volume II/24 presents the spectroscopic data on diamagnetic and paramagnetic molecules as well as on molecular ions and radicals up to date considering the publications up to and partly including 1997. The spectroscopic information collected in this volume has been obtained principally from gas phase microwave measurements. In addition, gas phase data have been included derived from methods related to microwave spectroscopy by employing a coherent radiation source.

Abstract: Volume II/25 is a supplemented and revised edition of the preceding volumes II/7, II/15, II/21 and II/23 containing up to date information on inorganic and organic polyatomic molecules. All experimental methods for the determination of quantitative structural data of free molecules have been considered: microwave, infrared, Raman, electronic and photoelectron spectroscopy as well as electron diffraction. The data obtained by these methods have been critically evaluated and compiled. They are presented separately for each molecule, together with a schematic figure of the structure and the original literature.

Abstract: This volume provides a comprehensive and evaluated compilation of nuclear magnetic resonance data. Chemical shifts and coupling constants of boron-11 and phosphorus-31 (subvol. A), fluorine-19 and nitrogen-15 (subvol. B), hydrogen-1 (subvol. C), carbon-13 (subvol. D), and oxygen-17 (subvol. E) compounds are tabulated together with the gross- and structure formulas and the most readily available solvents. Due to the large amount of the data merely chemical shifts are presented in the printed versions, and all the data, chemical shifts and coupling constants are provided on CD-ROM's.

Abstract: Volume III/7 contains structure data on those compounds which contain at least one of the elements F, Cl, Br, I, O, N, and P and cannot be called "organic". The structure data of the remaining inorganic compounds and the elements are dealt with in volumes III/6 and III/14, while the organic compounds are treated in volumes III/5 and III/10. The systematic arrange-ment is based on the anions ordered according to "key elements", since this system allows the arrangement of the crystal structure data in such a way that both chemical and crystallographical relationships can be recognized. Structure data are compiled as completely as possible for all inorganic substances, where crystal structures have been examined by means of X-ray, neutron, and electron diffraction,and for which at least the lattice constants have been determined.

Abstract: This subvolume contains selected data on heats of mixing and solution of binary gaseous, liquid, near-critical, and supercritical fluid systems of nonelectrolytes, including aqueous-organic systems, in broad ranges of temperature, pressure, and composition. All the data are extracted from the original literature published from 1957 to 2005. The names of the authors, the titles of the publications, and the exact references are given. Estimated uncertainties are reported. The printed volume presents tables for 314 representative systems. The CD-ROM displays all these data, as well as 134 additional data files, in PDF format and in fully documented computer readable standard electronic files (SELF and ELDATA)t. Moreover, the ELBT-program includes a comprehensive bibliographical database on heats of mixing and solution measurements published in the period 1853-2005 for 10867 two- to six-component systems consisting of organic or inorganic electrolytes and nonelectrolytes, ionic liquids, alloys, fused salts, polymers and other materials. The ELBT-program allows the fast search of data according to property type, chemical system (substances, mixtures, and solutions), author(s), source and year of publication. The software on the CD-ROM allows the correlation of the numerical data with several equations and the display of the original data and of the correlated data in tabular and graphical form. In order to facilitate the storage, exchange and use of the data, the ELBT-program of this volume allows importation of the information of SELF and ELDATA files, as well as of the files containing the results of correlations into Spreadsheet ML documents.

Abstract: Diffusion – defined as mass, amount, or particle transport process – is the most essential transport property besides viscosity and thermal conductivity. Diffusion is widely used in nature, technical and scientific applications, ranging from diffusion in all kinds of gases, liquids, solids, electrolytes and their mixtures. Due to the large amount of data, the volume LB IV/15 "Diffusion in Gases, Liquids, and Electrolytes" is divided into three subvolumes. Part A: Gases in Gases, Liquids and their Mixtures; Part B: Liquids in Liquids and Liquid Mixtures; Part C: Ions and Electrolytes in Liquids, Electrolytes and Molten Salts. The presented subvolume A includes the main chapters Measurement Methods, Diffusion in Pure Gases, Diffusion in Gaseous Mixtures, Diffusion of Gas/Vapor in Gases or Liquids and Diffusion of Gases in Solution. Due to the very different and widespread measurement methods, a precise description of these methods is given.

Abstract: Volume IV/1 contains information on the densities of liquid systems. It may be considered as a supplement to volume II/1 of the 6th Edition, which contains only a few data on nonaqueous systems. Data are not listed for all systems but primarily for those of greater interest where data for a larger range of concentrations were available.

Abstract: This critical compilation of virial coefficients of pure gases was prepared from the virial coefficient database at the Thermodynamics Research Center, formerly at Texas A&M University, College Station, Texas and now located at the National Institute of Standards and Technology, Boulder, Colorado. The virial coefficient data in this compilation will be of interest to the theoretical chemist as it includes the many sets of accurate gas imperfection data which have been determined over the past twenty years by improved methods of gas density determination, by isochoric Burnett coupling methods and from speed of sound measurements, as well as by the more traditional techniques.

Abstract: In the 6th Edition data on temperature, pressure,and the composition of liquids and vapor of boiling mixtures in thermodynamic equilibrium are contained in volumes II/2a and IV/4b. Volume IV/3 of the New Series supplements these tables, covering the literature from 1954 up to the beginning of 1974.
